Abstract

Ni-Ti base shape memory alloys (SMAs) are unique functional materials attractive for aerospace, medical and various engineering applications. The stability of the functional properties such as transformation temperatures, recovery stress and recovery strain of SMAs with thermo-mechanical cycling (TMC) is an important design13; criterion, and needs to be established before fabrication of any actuator. This paper deals with the results of an experimental study wherein the strain response of the Ni-Ti-Cu alloy wires on TMC have been reported.
